Abstract

The tricycle is steered by the seat, which acts on the rear wheels. It can travel forward or in reverse. The front wheel is smaller than the two rear wheels. The two rear wheels have independent brakes. The steering device consists of a steering column and a bowl-type seat. The frame can be folded. The main tube of the frame is adjustable.

Description

Es wird ein Fahrzeug vorgeschlagen, das im wesentlichen ein Gestell zur Aufnahme von drei Rädern, eine Tretkurbeleinrichtung und eine Lenkeinrichtung umfaßt.A vehicle is proposed which is essentially a frame to hold three wheels, comprises a pedal crank device and a steering device.

Die Lenkeinrichtung, die in Fahrtrichtung auf zwei hintere Räder wirkt, ist gleichzeitig Sitz.The steering device, which acts on two rear wheels in the direction of travel, is seat at the same time.

Das in Fahrtrichtung vordere Rad wird mittels einer Tretkurbeleinrichtung angetrieben. Zusätzlich besteht die Version mit Handkurbelbetrieb.The front wheel in the direction of travel is driven by a pedal crank mechanism. In addition, there is the version with hand crank operation.

Das Fahrzeug kann auch rückwärts fahren.The vehicle can also drive in reverse.

Die Treteinrichtung umfaßt ein mit einem Pedalpaar versehenes Kettenrad, mit dem über eine Rollenkette das vordere Rad über ein Ritzel angetrieben wird.The pedal device comprises a chain wheel provided with a pair of pedals, with the front wheel via a sprocket via a roller chain is driven.

Desweiteren besteht die Möglichkeit, das vordere Rad durch einen Gummiriemen anzutreiben.There is also the option of driving the front wheel with a rubber belt.

Die Lenkeinrichtung besteht aus einer Lenksäule, die im Gestell drehbar gelagert ist und an dessen oberen Ende sich der Sitz befindet.The steering device consists of a steering column that can be rotated in the frame is stored and at the upper end of the seat is.

Der Lenkvorgang wird durch abbremsen des kurvenäußeren Rades eingeleitet.The steering process is initiated by braking the wheel on the outside of the curve.

Das Hauptrahmenrohr ist verstellbar, so daß sich Einsatzmöglichkeiten für unterschiedliche Körpergrößen bieten.The main frame tube is adjustable so that it can be used for different purposes Offer body sizes.

Das Gestell ist klappbar ausgeführt, so daß in zusammengeklapptem Zustand das alleinstehende Rad zwischen den beiden anderen Rädern zu liegen kommt.The frame is foldable, so that when folded the single wheel comes to rest between the other two wheels.

Die Tretkurbeleinrichtung ist verstellbar angebracht, so daß Personen mit unterschiedlichen Beinlängen zufriedenzustellen sind.The pedal crank device is adjustable so that people with different leg lengths are to be satisfied.

Jedes Rad kann einzeln gefedert sein, durch Gummilagerung, Schrauben- oder Blattfederung.Each wheel can be individually sprung, by rubber bearings, screw or leaf suspension.

Maßgebend für folgende Größenangaben ist das Modell für ausgewachsene Menschen, wobei diese Angaben je nach Einsatzzweck variabel sind:
Die beiden hinteren Räder haben einen Durchmesser von 20''
Antriebsrad: Größe 20'' oder größer
Die Entfernung von Tretlager zu Sitzlehne beträgt 1100 Millimeter
Die Sitzhöhe beträgt 450 Millimeter
Außenbreite (Spurweite der Hinterräder) 900 mm
Gesamtlänge 1500 mm The model for adult people is decisive for the following size information, whereby this information is variable depending on the purpose:
The two rear wheels have a diameter of 20 ''
Drive wheel: size 20 '' or larger
The distance from the bottom bracket to the seat back is 1100 millimeters
The seat height is 450 millimeters
Outer width (track width of the rear wheels) 900 mm
Overall length 1500 mm

Durch diese Neukonstruktion ergeben sich unter anderem folgende Vorteile:
Verhalten wie Einspurfahrzeug; kein Abheben eines Rades bei Kurvenfahrt
Kurvenleger
durch Frontantrieb effizienter Krafteinsatz und Fahrstabilität gewährleistet
niedriger Schwerpunkt
bequeme, übersichtliche Sitzposition
durch wenige und kurze Rohre des Gestells geringes Gewicht
durch kurzen Radstand bei Ausnutzung des vollen Lenkeinschlags sehr kleiner Wendekreis - etwa 2,2 Meter
durch zusätzliche Rückwärtsfahrtmöglichkeit äußerst wendig
auch Rückwärts sehr sicheres Fahrverhalten
bei Rückwärtsfahrt sehr viel Kraft einsetzbar (Bergfahrt)
günstige Parkmöglichkeit
sehr gute Aerodynamik durch geringe Bauhöhe und kleine Frontfläche
Das Fahrzeug kann auch für mehrere Personen ausgelegt werden.
Das Fahrzeug kann mit einem Gehäuse versehen werden,The advantages of this new construction include the following:
Behavior like single-track vehicle; no lifting of a wheel when cornering
Curve layer
Front-wheel drive ensures efficient use of power and driving stability
low center of gravity
comfortable, clear sitting position
low weight due to few and short tubes of the frame
thanks to the short wheelbase and full steering angle, very small turning circle - around 2.2 meters
extremely manoeuvrable thanks to additional reversing option
also very safe driving behavior in reverse
a lot of power can be used when driving backwards (ascent)
cheap parking
very good aerodynamics due to low height and small front surface
The vehicle can also be designed for several people.
The vehicle can be provided with a housing,

Mit Hilfe der patentierten Erfindung der Sitzlenkung erübrigt sich ein Steuerrad oder ein Lenker, der Richtungswechsel findet durch Gewichtsverlagerung statt.With the help of the patented invention of the seat steering, there is no need for a steering wheel or a handlebar, the change of direction takes place through weight shift.

Um diese neue Lenkeinrichtung vorzustellen, wurden zunächst Skizzen angefertigt und daraufhin Modelle hergestellt.In order to present this new steering device, sketches were first made and then made models.

Diese Modelle, die im Maßstab 1 : 1 existieren, ähneln dreirädrigen Fahrrädern und können am Straßenverkehr eingeschränkt teilnehmen.These models, which exist on a 1: 1 scale, are similar to three-wheeled bicycles and can be used on Participate in restricted traffic.

Sie dienen allerdings lediglich zur Kenntlichmachung der neuen Steuerung, die durchaus auch für motorgetriebene Fahrzeuge, Boote und Flugzeuge geeignet ist.However, they are only used to identify the new control system, which is certainly also is suitable for motor vehicles, boats and planes.

Zum Beispiel lenkt man ein Fahrrad beim freihändigen Fahren durch Gewichtsverlagerung, PKW-Insassen neigen sich zur Kurve hin und erfahrene Piloten wissen, daß am Besten mit dem Hinterteil gesteuert wird. Dieses ist an sich nichts Neues, jedoch wurde das Wissen noch nicht in die Tat umgesetzt.For example, you steer a bike while moving hands-free by shifting your weight, Car occupants lean towards the bend and experienced pilots know that they are best with the rear is controlled. This is nothing new in itself, however, the knowledge has still not implemented.

Die mit den bisher gefertigten Fahrzeugen unternommenen Fahrversuche haben wiederum zu interessanten Erkenntnissen geführt, so daß neue Zeichnungen erstellt worden sind und der nächste Prototyp mit optimierter Geometrie und gefälligem Design entstehen könnte.The driving tests undertaken with the vehicles manufactured to date have again increased interesting insights, so that new drawings have been created and the next prototype with optimized geometry and pleasing design could arise.

Zusätzlich zu den oben beschriebenen Einsatzfeldern gäbe es nun auch die Möglichkeit, die Fahrzeuge als Behindertenhilfe zu nutzen.In addition to the fields of application described above, there is now also the option of to use the vehicles as a handicap assistance.
